Cannot Clear NVRAM

Acer Chromebook 15 (CB3-531) Banjo Baytrail - Screw Removed
Full ROM / UEFI MrChromebox - 4.22.0
Running Linux Mint XFCE. Everything works as expected.
However, I just clean installed switching from Xubuntu and now I notice boot errors about region and communicating with TPM. So, I updated to 4.22.0. I tried to clear the NVRAM and it errors out. If I enable the TPM chip, then I cannot run the script updater. With TPM disabled, everything works. I just cannot clear the NVRAM. It isn’t a huge deal. I’m just not sure what I am doing wrong.

what do you mean by clearing the NVRAM? Via the script function? That has nothing to do with the TPM

That is correct. This is the error I get.
